Internet of Things concept, understanding

If you wish to make your career in network, the Certifications is considered to be the best certification, to jump-start your career. But gaining this certification isn’t considered to be that much easy. You have to go through lots and lots of study process unless you have the help of the CCNP 300 715 SISE Dumps offered at the ITCertDumps.

1. The birth of the Internet of Things concept

In 1991, the Chief Scientist of Xerox Company, the Chief Scientist of Xerox, published “21st Century Computer” in “Science American” magazine (“The Computer for “) One article, a bold forecast for the future development of the computer. In the text, he pioneered the idea of ??”UC, Ubiquitous Computing), and believes that the computer will develop to ordinary things, and people can enjoy all services, computer technology, anytime, anywhere. Finally, it will be seamlessly integrated into daily life.

In 1995, US Microsoft Company jointly founder Bill Gates has such a wonderful description in his book “The Road” of the future — “When you walk into the airport gate, your pocket individual Computers with the airport will confirm that you have bought a ticket; and the camera you lost or stolen will automatically send it back information, tell the user to now the specific location, even when it is in different cities Time … “Bill Gats is hereby assumption that” Internet “is the idea of” Internet “. However, it is limited to the development level of wireless networks, hardware and sensing equipment at that time, and his beauty assumption did not attract people at the time.

In 1999, at the US Motto and Network International Conference, Professor Kevin Ashton, the MIT Auto-ID Center, was studying RF identification ( RFID) Technical combined with item coding, RFID, and Internet technology have first proposed the concept of “Internet of Things”, and he is also called “the father of the Internet of Things”.

2005, the International Telecommunications Union (ITU) officially identified the concept of “Internet of Things” on the Information Society (WSIS) held by Tunisia, and issued “ITU Internet Report 2005: The definition of more recognized “Internet of Things” is given in the networking report: the Internet of Things is through the intelligent sensor, radio frequency identification (RFID) equipment, satellite positioning system, etc. Get up, exchange information exchange and communication to achieve a network of intelligent identification, positioning, tracking, monitoring, and management of items. Obviously, the Internet of Things is to be implemented, interconnect, sharing, interoperability between the objects, and thus is also known as “Internet”, and the English name is “Internet of Things”.

As the high integration and comprehensive application of the new generation of information technology, the Internet of Things has received attention from all walks of life and is also considered to be the third information technology revolution after the computer and the Internet. Currently, the Internet of Things has been applied to warehousing logistics, urban management, traffic management, energy power, military, medical and other fields, and is widely involved in all aspects of national economy and social life.

II, the Internet of Things

Internet of Thing, IoT) is generalized, light from the literal, all things can be connected to the network, but the light is online Not enough, imagine that if these fixations can be more wisdom, they can communicate with each other to facilitate our lives, this is the most important origin of the birth of the Internet of Things, just like we watch technology movies, indoors Air conditioning can be automatically opened according to the current temperature, let us enjoy the heating at home, not to rely on artificial remote control and remote settings. Or after you go to the hospital for inspection, the machine automatically passes the check results into the database, and performs real-time comparison of relevant sickness and data to transfer the results of the surrounding, rather than every exquisite data and whether it exceeds Warning value.

The concept seems simple, but in fact, the middle contains several important elements:

The first of course is intelligent, such as in smart TV, only on the surface Or TV equipment, but he itself can have a multi-task-handed category that is not to watch the basic features such as TV, but also search program, subscription, collection, etc., such equipment itself is actually a TV function. Small computer, like some bracelets, can match the effect of the music, this is of course the giving of the worship, and this intelligent key is in the chip, of course the intelligence required by each device. The conditions will be different. For example, in wear equipment, the center of gravity will be low power consumption, thin and small, accurate, which is of course also close to the use of the product.

The second element is the so-called online capabilities and communication technology, and a large element of intelligent is to enable the device to have online power. On the current trend, through various equipment connected opportunities It has been greatly improved, and only some of the products are still our familiar equipment, but after the online ability, the services provided will greatly improve, like the smart refrigerator that is now launched, you can scan and connect The way, to record what you have in your refrigerator.

But some equipment is to pursue lightweight, embedding, the smaller the equipment, and if necessary, the computing resources needed to connect to the Internet are too heavy, so they will abandon the actual With the ability to actually connect to the Internet, but with a lighter communication protocol (such as Bluetooth, low-power Bluetooth, GPS, NFC or RFID), and so-called gateway device (Gateway), and Gateway equipment to the external network. And such gateway devices have a pair of capabilities, in addition to the ability to manage these objects, but also provide these small objects to external network communication, this is why ColdPlay concerts can achieve a dazzling effect The big strength.

and some of the objects of the network, because there is no so-called display interface, of course, there will be no input control channels on the interaction, so it is like a acquisition information, control …, etc., in addition to the computer, handheld Equipment is also an important way to do connection through tablets and scan guns, through the APP on the tablet, but this is not the most important factor in the equipment.

So, the third element is on the cloud service of the device, the main purpose of the network can be transferred to the cloud, and “service” is pending, everyone must have a mobile phone. Abstract is an APP of 85 degrees C, through the scanning reception order, checkout …, etc., and transfer the consumption record to the mobile member system (CRM), and the combination of the membership bonus, etc., all the Internet of Things In the “service”, but calculation and service, it will always be implemented on the cloud, so the status of the cloud service in the Internet of Things is always the

because the light is connected to the network and equipment. To collect data, it is definitely not our intention, from the sensor or the data (data) collected by the scanner, through the service (INFORMATION), but the light is not satisfied, how to analyze and Methods such as machine learning, transforming information into knowledge and intelligence (WiSDOM), which is intelligent, even networkization, and service. Just like the smart refrigerator light is not enough record inventory, if you can remind low inventory in real time, and even automatically go to the e-commerce website, this convenient, I think it is our most expectation.

declaration, the article is from the Internet Shangdi Zhiku Wei Qiang and blog artificial intelligent lovers knowledge sharing, it feels good, leading to record.

Although no system is ever 100 percent protected, the ability for differentiating between typical network traffic as well as potentially harmful malware is considered crucial and provides the focus of this associate-level certification path. Also, if you wish to acquire this certification, you should gain the CCNP 300 730 SVPN Dumps, which are being offered at the ITCertDumps.
